* On Hold
- NIH has received public comment on a proposed change to the definition of “human embryonic stem cells” in the NIH Guidelines for Human Stem Cell Research. While NIH is considering those public comments on the proposed change, this hESC line is currently on hold and should not be used in NIH-funded research. If grantees are currently using any of these lines they may contact the NIH Institute or Center that is funding their project for further information.
